Ghostly Cat’s Head Nebula Lurks Within Sight of NASA’s Hubble, Webb

October 29, 2026

$Visible-light image of the Cat’s Head Nebula by the Hubble Space Telescope. A dark brown, opaque filament of dust is in the center, stretching from the bottom to almost the very top. It has a narrow, irregular shape that resembles a cat sitting with its back toward the viewer. The cat’s head is turned toward the right, revealing a red glowing eye. The background is bright blue. The image is dotted with many small stars. Some larger stars with the telescope’s characteristic four-point diffraction spikes are scattered in the background and foreground.$
Webb Measures Distance to Farthest Fast Radio Burst, Suggesting Origin

October 08, 2026

$A field full of small galaxies of all shapes against the blackness of space. A few bright white stars show 8 prominent diffraction spikes. A small galaxy at lower right is highlighted with a white box. A shaded triangle extends upward to the corners of a larger box showing a zoom in of the region. Two fuzzy, light blue blobs are at center, with a larger and brighter one at top. Just above the top blob is a white crosshair showing the location where a fast radio burst was detected.$
NASA's Webb Captures Commotion From Nebula’s Stellar Jets

October 06, 2026

$A young star cluster filled with many stars that display Webb’s unique eight-pronged diffraction pattern. At its center is a yellow star which sports the largest diffraction pattern. To the left of the star, there is a region filled with yellow dust and gas that extends from the star to bottom left half of the image. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust. The top left corner, which lies outside the yellow region, has a few bright protostars, within dense gray gas. These stars illuminate the gas, making it appear blue. A few red outflows from other protostars are visible above this grayish-blue region. To the right of the central star, there is a clumpy, flame-like plume of red dust and gas with protostars that emit a soft white light within. The plume is surrounded by more dense gray gas and dust. It is about one third the size of the yellow region.$
